BACKGROUND & AIMS: Eosinophilic esophagitis (EoE) is often detected in children and is considered to be a rare disease, with prevalence values reported to be below 60 cases per 100,000 persons. To determine whether the incidence of EoE in children in Utah exceeds estimates from regional reports, we calculated incidence and prevalence values over a 5-year period. METHODS: Using consensus guidelines for the diagnosis of EoE, we reviewed pathology records from in the Intermountain Healthcare pathology database, from July 1, 2011 through June 31, 2016...

Curimatidae, the fourth largest family of detritivorous Neotropical characiform fishes, encompasses eight extant genera and over 110 species dwelling in diverse freshwater habitats from Costa Rica to Argentina. Extensive phylogenetic analyses of soft anatomy and osteology provided evidence for intergeneric and most interspecific relationships, and formed the basis of curimatid taxonomy for nearly 40 years. However, that morphological phylogeny demonstrated incomplete phylogenetic resolution at various scales and has never been tested with extensive molecular data...

The pharmaceutical industry has entered in a new era, as there is a growing interest in increasing the quality standards of dosage forms, through the implementation of more structured development and manufacturing approaches. For many decades, the manufacturing of drug products was controlled by a regulatory framework to guarantee the quality of the final product through a fixed process and exhaustive testing. Limitations related to the Quality by Test (QbT) system have been widely acknowledged. The emergence of Quality by Design (QbD) as a systematic and risk-based approach introduced a new quality concept based on a good understanding of how raw materials and process parameters influence the final quality profile...

Inhibitory control refers to the ability to stop, change or delay a response, and is often used in order to protect higher order goals. Theoretical models suggest that appetitive cues such as pictures of alcoholic drinks or food evoke strong automatic appetitive responses which lead to transient impairments in inhibitory control, and that these effects of cues may be related to individual differences (e.g. in body mass index, or alcohol consumption). In order to investigate these claims we conducted a random effects meta-analysis of 66 effect sizes (35 alcohol, 31 food) from 37 articles that tested the effect of exposure to appetitive (alcohol/food) cues on indices of inhibitory control...

INTRODUCTION: Helicobacter pylori infection might increase risk of dementia, but available evidence is inconsistent, and longitudinal studies are sparse. We investigated the association between H. pylori serology and dementia risk in a population-based cohort. METHODS: Between 1997 and 2002, we measured H. pylori serum IgG titers in 4215 nondemented participants of the Rotterdam Study with a mean age of 69 years. We determined the association between H. pylori at baseline and dementia incidence until 2015, per natural log (U/mL) increase in titer, and for seropositive/seronegative, using Cox models adjusting for cohort, sex, age, education, and cardiovascular risk factors...

Increasing evidence shows that thinner retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL), assessed on optical coherence tomography (OCT), are reflecting global brain atrophy. Yet, little is known on the relation of these layers with specific brain regions. Using voxel-based analysis, we aimed to unravel specific brain regions associated with these retinal layers. We included 2,235 persons (mean age: 67.3 years, 55% women) from the Rotterdam Study (2007-2012) who had gradable retinal OCT images and brain magnetic resonance imaging (MRI) scans, including diffusion tensor (DT) imaging...

BACKGROUND: Previous studies have shown that foamy viral (FV) vectors are a promising alternative to gammaretroviral and lentiviral vectors and insulators can improve FV vector safety. However, in a previous analysis of insulator effects on FV vector safety, strong viral promoters were used to elicit genotoxic events. Here we developed and analyzed the efficacy and safety of a high-titer, clinically relevant FV vector driven by the housekeeping promoter elongation factor-1α and insulated with an enhancer blocking A1 insulator (FV-EGW-A1)...

Several studies have been conducted regarding the prevalence of Chlamydia trachomatis, Mycoplasma hominis, and Ureaplasma urealyticum in pregnant Iranian women. However, it is necessary to combine the previous results to present a general assessment. We conducted the present study based on systematic review and meta-analysis studies according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched the national and international online databases of MagIran, IranMedex, SID, MedLib, IranDoc, Scopus, PubMed, ISI Web of Knowledge, and Google Scholar search engine for certain MeSH keywords until June 16, 2017...

BACKGROUND: Postoperative pancreatic fistula is one of the most frequent and potentially life-threatening complications following pancreatic resections. Fibrin sealants are introduced to reduce postoperative pancreatic fistula by some surgeons. However, the use of fibrin sealants during pancreatic surgery is controversial. This is an update of a Cochrane Review last published in 2016. OBJECTIVES: To assess the safety, effectiveness, and potential adverse effects of fibrin sealants for the prevention of postoperative pancreatic fistula following pancreatic surgery...

Mental health policy stipulates seclusion should only be used as an intervention of last resort and for the minimum possible duration. Current evidence details which service users are more likely to be secluded, why they are secluded, and what influences the decision to seclude them. However, very little is known about the decision to release service users from seclusion. An integrative review was undertaken to explore the decision-making processes of mental health professionals which guide the ending of seclusion...

REVIEW
Stasia Rouse, Matthew Wodziak
PURPOSE OF REVIEW: Hiccups are a common problem that crosses multiple disciplines including neurology, gastroenterology and pulmonology, and primary care. There are no formal guidelines to the treatment of intractable hiccups and treatment is based on experience and anecdotal evidence often relying on older medications. We have reviewed the relevant literature with an emphasis on the last five years or so in management of intractable hiccups. RECENT FINDINGS: The production of hiccups is a complex mechanism which involves multiple neurotransmitters and anatomical structure within the central and peripheral nervous system...

In psoriasis, several patient-relevant treatment goals must be met to be able to consider a treatment beneficial. To assess treatment benefit, the validated questionnaire Patient Benefit Index (PBI) can be used. Its global score summarizes the degree of patient-relevant treatment goals achieved after treatment, weighted by their individual importance on rating scales. These treatment goals have empirically been assigned to five dimensions. While the weighting procedure of the PBI provides information about the importance patients attach to treatment goals on a rating scale from 0 to 4, methods of preference elicitation provide information on how patients would trade off certain treatment goals against each other...

Mitochondria are essential organelles, found within eukaryotic cells, which contain their own DNA. Mitochondrial DNA (mtDNA) has traditionally been used in population genetic and biogeographic studies as a maternally-inherited and evolutionary-neutral genetic marker. However, it is now clear that polymorphisms within the mtDNA sequence are routinely non-neutral, and furthermore several studies have suggested that such mtDNA polymorphisms are also sensitive to thermal selection. These observations led to the formulation of the "mitochondrial climatic adaptation" hypothesis, for which all published evidence to date is correlational...

Autism spectrum disorder (ASD) has captured the attention of scientists, clinicians and the lay public because of its uncertain origins and striking and unexplained clinical heterogeneity. Here we review genetic, genomic, cellular, postmortem, animal model, and cell model evidence that shows ASD begins in the womb. This evidence leads to a new theory that ASD is a multistage, progressive disorder of brain development, spanning nearly all of prenatal life. ASD can begin as early as the 1st and 2nd trimester with disruption of cell proliferation and differentiation...

Burns are a relatively common injury in children accounting for over 50 000 emergency department attendances each year. An estimated 1 in 10 of these are due to maltreatment. These may present in the form of physical abuse or neglect with a reported ratio of 1:9. A burn associated with maltreatment may be a marker for future abuse or neglect and it is paramount that concerns are identified and addressed at the initial visit. Paediatricians need to be confident to identify safeguarding concerns specific to childhood burns and investigate accordingly...

Animal-associated microorganisms ('microbiota') dramatically influence nutritional and physiological traits of their hosts. To expand our understanding of such influences, we predicted bacterial genes that influence a quantitative animal trait by a comparative genomic approach and extended these predictions via mutant analysis. We focus on D. melanogaster starvation resistance (SR). We first confirmed that D. melanogaster SR responds to the microbiota by demonstrating that bacteria-free flies have greater SR than flies bearing a standard 5-species microbial community, and extended this analysis by revealing species-specific influence of 38 genome-sequenced bacterial species on D...

The failure of DNA ligases to complete their catalytic reactions generates cytotoxic adenylated DNA strand breaks. The APTX RNA-DNA deadenylase protects genome integrity and corrects abortive DNA ligation arising during ribonucleotide excision repair and base excision DNA repair, and APTX human mutations cause the neurodegenerative disorder ataxia with oculomotor ataxia 1 (AOA1). How APTX senses cognate DNA nicks and is inactivated in AOA1 remains incompletely defined. Here, we report X-ray structures of APTX engaging nicked RNA-DNA substrates that provide direct evidence for a wedge-pivot-cut strategy for 5'-AMP resolution shared with the alternate 5'-AMP processing enzymes POLβ and FEN1...
